Rest-stress myocardial arterial spin labeled (ASL) MRI
was performed in twenty-nine patients with suspected coronary artery disease
(CAD).Perfusion reserve was estimated
in six myocardial segments of a single mid short-axis slice, and compared
with X-ray angiography. Receiver operating characteristic (ROC) curves were
analyzed for (i) detection of patients with angiographic CAD and (ii)
detection of the most ischemic segments. The area under ROC curves were (i)
0.88 and (ii) 0.71.
